As shown in Figure 1, artificial hair of the present invention is to use the ratio of length (L) of the discharging guide groove of the diameter (D) of nozzle bore 2 and nozzle bore 2 with polyvinyl chloride fiber: L/D is 1～3, the thickness of nozzle introduction part 1 is 4mm or more than the 4mm, and, it to the final importing angle of the nozzle bore 2 in this nozzle introduction part 1 20 °～90 ° nozzle 10, discharge with the per unit nozzle bore is 65～165g/h, spinning poly vinyl chloride resin composition and the artificial hair polyvinyl chloride fiber that obtains.And, artificial hair polyvinyl chloride fiber of the present invention, the arithmetic average roughness (Ra) according to JIS B0601 regulation of its length direction is 0.18～0.38 μ m, and this artificial hair is 0.5～3.5 μ m with the maximum height (Ry) according to JIS B 0601 regulation of the length direction of polyvinyl chloride fiber.
The value of above-mentioned arithmetic average roughness (Ra) and maximum height (Ry), be by the value of using the microscopical measured value of non-contact laser to calculate, as the evaluating apparatus that can measure like this, can enumerate, for example the non-contact laser microscope VK-8500 that makes of KEYENCE Co., Ltd. etc.
And above-mentioned arithmetic average roughness (Ra) and maximum height (Ry) can use the calculating formula of JISB 0601 regulation to calculate.Promptly, " arithmetic average roughness (Ra) " is to be X-axis in the average line direction with the roughness curve among the length direction 300 μ m, and with the direction vertical with X-axis is Y-axis, and with y=f (x) expression during roughness curve, the value that will be tried to achieve by following mathematical expression 1 is with micron
In addition, above-mentioned " maximum height (Ry) " be in the direction detection vertical with roughness curve at the summit line (mountain Top Line) of the roughness curve of length direction 300 μ m and the interval of valley line (the lowest point Line), and will be worth with the value represented of micron (μ m).Below, in this manual, Ra and Ry are the values of measuring at the length direction of fiber.
The front-end architecture of the nozzle of spinning poly vinyl chloride resin is owing to can bring influence to the mixing state of polyvinyl chloride resin, therefore, when L/D than 1 hour, it is big that the turbulent flow of the fusion polyvinyl chloride resin of extruding from spray nozzle front end becomes, so Ra is bigger than 0.38, and Ry is bigger than 3.5, therefore is easy to generate fracture of wire.In addition, when L/D was bigger than 3, because the fusion polyvinyl chloride resin that spray nozzle front end is extruded is a laminar flow, so Ra is littler than 0.18, and Ry was littler than 0.5, so the gloss grow, and the sense of touch variation.Little and L/D is the structure of using always than the front-end architecture of 3 big nozzles when the spinning of polyethylene terephthalate (PET) and polypropylene (PP) to L/D than 1, but in polyvinyl chloride resin (PVC), because it is big that the melt viscosity of resin becomes, and resin is pressed and is become big, so it is big that the influence of spray nozzle front end structure becomes, therefore, specific L/D becomes key.Therefore, in the present invention, L/D is 1～3.That is, want to obtain common polyvinyl chloride fiber, the L/D in the nozzle of spinning poly vinyl chloride resin is 4～10.
In general, because that the resin of polyvinyl chloride resin is pressed is big, L/D hour, can not keep the intensity of nozzle.Therefore, in order to obtain the artificial hair polyvinyl chloride fiber, need the thickness of specific importing angle and nozzle introduction part to nozzle bore.Than 20 ° hours, because the molten resin that spray nozzle front end is extruded is a laminar flow, so Ra is littler than 0.18, and Ry was littler than 0.5, so the gloss grow, and the sense of touch variation to the importing angle of nozzle bore.In addition, to the importing angle of nozzle bore when bigger, become big, can not keep the intensity of nozzle, and the value of Ra and Ry also becomes big because the resin of nozzle pressed than 90 °.In addition, nozzle thickness is 4mm or 4mm when following, because nozzle strength reduces, nozzle is damaged.In the present invention, be 20 °～90 ° to the final importing angle of nozzle bore, and the thickness of nozzle introduction part is 4mm or more than the 4mm.
The discharge of per unit nozzle bore than 65g/h after a little while because the mixing of polyvinyl chloride resin run smooth, so Ra is littler than 0.18, and Ry is littler than 0.5, so the gloss grow, and the sense of touch variation.In addition, than 165g/h for a long time, because the mixing of polyvinyl chloride resin becomes insufficient, so Ra is bigger than 0.38, and Ry is bigger than 3.5, therefore, the sense of touch variation of fiber, and the reduction of the intensity of fiber, in addition, spinnability is variation also.Therefore, in the present invention, the discharge of per unit nozzle bore is 65～165g/h, preferred 80～150g/h.That is, in the present invention, be 65～165g/h by the discharge that makes the per unit nozzle, control polyvinyl chloride resin mixing state, make at fiber surface concavo-convex, thereby can control gloss, sense of touch and feel.
Like this, a kind of poly (vinyl chloride) fiber for artificial hair can be provided, this poly (vinyl chloride) fiber for artificial hair is to use the ratio of length (L) of the discharging guide groove of the diameter (D) of nozzle bore 2 and nozzle bore 2: L/D is 1～3, the thickness of nozzle introduction part is 4mm or more than the 4mm, and, it to the final importing angle of the nozzle bore 2 in this nozzle introduction part 1 20 °～90 ° nozzle 10, discharge with the per unit nozzle bore is 65～165g/h, spinning poly vinyl chloride resin composition and the artificial hair polyvinyl chloride fiber that obtains, when this artificial hair is 0.18～0.38 μ m with the arithmetic average roughness (Ra) according to JIS B 0601 regulation of the length direction of polyvinyl chloride fiber, and, when this artificial hair is 0.5～3.5 μ m with the maximum height (Ry) according to JIS B 0601 regulation of the length direction of polyvinyl chloride fiber, can keep the intensity of fiber and the mouldability of fiber, and have the such gloss of natural hair, the feel of sense of touch and nature.
As shown in Figure 2, artificial hair of the present invention with polyethylene kind fiber 20 in, with the max line segment length 13 of passing through center of gravity in the cross section as Mmax (mm), with sectional area 11 as S (mm
2) and with periphery length 12 during as L (mm), the value that makes (LMmax)/S is in 4.2～7.0 the scope.These artificial hairs can use above-mentioned non-contact laser microscope to measure with Mmax (mm), sectional area (11) and the periphery length (12) of the max line segment length 13 of passing through center of gravity in the cross section of polyvinyl chloride fiber 20.
Like this, when with above-mentioned artificial hair with the max line segment length 13 of passing through center of gravity in the cross section of polyvinyl chloride fiber 10 as Mmax (mm), with sectional area 11 as S (mm
2) and with periphery length 12 during, be in 4.2～7.0 the scope if make the value of (LMmax)/S as L (mm), the durability that can not can make fibre strength and nozzle reduces and makes the fibre section shape that suppresses gloss more.(LMmax)/value of S is than 4.2 hours, because the diffuse reflection of light can fully not take place, therefore has the inhibition effect of the gloss inadequate worry that becomes, and when bigger than 7.0, has the durability of nozzle or fibre strength to reduce, perhaps spinnability situation about reducing.
In other words, above-mentioned artificial hair is with the max line segment length 13 of passing through center of gravity in the cross section of polyvinyl chloride fiber 10 and periphery length 12 is big more, sectional area 11 is more little, and (LMmax)/value of S is big more, fibre section shape concavo-convex many, become the shape of flat flat (い び つ), therefore, can become the fibre section shape that suppresses gloss more.
In the present invention, above-mentioned polyvinyl chloride resin composition preferably is made of 100 parts by mass polyvinyl chloride resins, 0.3～3.0 parts by mass high-grade aliphatic ester series lubricant agent (a) and 0.3～1.5 parts by mass polyethylene kind lubricant (b), and (a) and match ratio (b): (a)/(b) be 0.5～4.Like this, when above-mentioned polyvinyl chloride resin composition is made of 100 parts by mass polyvinyl chloride resins, 0.3～3.0 parts by mass high-grade aliphatic ester series lubricant agent (a) and 0.3～1.5 parts by mass polyethylene kind lubricant (b), and match ratio (a) and (b): (a)/(b) be 0.5～4 o'clock, can provide and keep fibre strength and fiberizing, and have the artificial hair polyvinyl chloride fiber of the feel of the such gloss of natural hair, sense of touch and nature.
High-grade aliphatic ester series lubricant agent and polyethylene kind lubricant use separately respectively, and the rubbing action that reduces resin and make-up machine surface is strong, forms granular piece at fiber surface, and sense of touch is reduced.Though it is also indeterminate for its reason, if but also with high-grade aliphatic ester series lubricant agent and polyethylene kind lubricant, the effect grow that the higher fatty acids series lubricant agent alleviates the friction between resin particle, thus can make have the such gloss of natural hair, the fiber surface shape of feel of sense of touch and nature.
High-grade aliphatic ester series lubricant agent (a) preferred alcohols that the present invention uses or the fatty acid ester of polyalcohol, but, also can use these known lubricants in addition as long as without prejudice to purpose of the present invention.Particularly, can be fixed oil, butyl stearate, glyceryl monostearate, pentaerythritol tetrastearate, stearic stearolactone etc., also can be their mixture more than 2 kinds or 2 kinds.
The cooperation quantitative change of above-mentioned high-grade aliphatic ester series lubricant agent (a) for a long time, arithmetic average roughness (Ra) and maximum height (Ry) are the tendency that diminishes.The use level of above-mentioned high-grade aliphatic ester series lubricant agent (a) is 0.3～3 parts by mass with respect to polyvinyl chloride resin 100 parts by mass preferably.During its use level less than 0.3 parts by mass,, can not fully carry out the mixing of polyvinyl chloride resin, therefore, form granular piece, the worry that has sense of touch to reduce at fiber surface because the rubbing action that inhibition polyvinyl chloride resin particle is asked dies down.When its use level surpasses 3 parts by mass, the rubbing action that alleviates polyvinyl chloride resin and make-up machine that is caused by the high-grade aliphatic ester series lubricant agent became strong, therefore can not fully carry out the mixing of polyvinyl chloride resin, therefore, the worry that causes spinnability to reduce be arranged.
As long as the preferred mean molecule quantity of the polyethylene kind lubricant (b) that the present invention uses is 2000～6000, and density is 0.95～0.98 high density polyethylene (HDPE) series lubricant agent, but without prejudice to purpose of the present invention, can use the known lubricant beyond these.
In addition, the cooperation quantitative change of polyethylene kind lubricant (b) for a long time, arithmetic average roughness (Ra) and maximum height (Ry) have the tendency that becomes big.The use level of this lubricant (b) is 0.3～1.5 parts by mass with respect to polyvinyl chloride resin 100 parts by mass preferably.During use level less than 0.3 parts by mass of polyethylene kind lubricant (b), because the mixing excessive developments of polyvinyl chloride resin, not only can not suppress gloss, the situation that the sense grow that slides is also arranged on sense of touch, and polyethylene kind lubricant (b) is when surpassing 1.5 parts by mass, because the mixing of polyvinyl chloride resin can not be carried out fully, forms granular piece at fiber surface, the situation that causes sense of touch to reduce is arranged.
The cooperation ratio (a)/(b) of high-grade aliphatic ester series lubricant agent (a) and polyethylene kind lubricant (b) is preferably 0.5～4.During cooperation ratio (a)/(b) less than 0.5, owing to alleviate the rubbing action grow in the device for spinning, mixing the becoming of polyvinyl chloride resin can not be carried out fully, therefore, form granular piece at fiber surface, the situation that causes sense of touch to reduce is arranged, and, if cooperation ratio (a)/(b) is bigger than 4, the rubbing action that alleviates polyvinyl chloride resin and device for spinning surface that is caused by the high-grade aliphatic ester series lubricant agent became strong, therefore can not carry out the mixing of polyvinyl chloride resin fully, therefore, cause spinnability to reduce sometimes.
Control the method for value of the surface roughness of polyvinyl chloride fiber of the present invention, the method of adjusting above-mentioned lubricant is not only arranged, can also be for example by combination, the method for the method of adjusting with other additive, the condition of molding when adjusting moulding and the known method such as method of passing through the post processing of fiber.
